This one was tricky; I honestly am not 100% sure but I think it's a required
property. I added it to the required properties as I see it used on every
implementation for this chip.

I don't think this is common for all, I believe it is optional for some. If I
am not mistaken this is because there is a button connected to the PMIC that
is used to wake/suspend/poweron/poweroff the device. I put it under optional
for now as I'm not sure if every device has this or not.
